Finding pH of solution?

Question

[H ]=1 x 10^-5 M what is the pH?

any help please! thanks!

Answer 1

-log (1 x 10^-5)

Although this is easy because the answer would just be 5

Like

[H+] = 10^-1 is a pH of 1

[H+] = 10^-2 is a pH of 2

etc.

Answer 2

negative log function of the [H]

have fun, chemistry, lo;

Answer 3

If you have a log table nearby, the quickest way to do these problem is :  Given [H+]= n x 10^-m, pH= 5-log n.
